1) If tcp_{sendmsg,sendpage} tacks on more data to an
   existing SKB, this can make tso_factor inaccurate.
   Invalidate it, which forces it to be recalculated,
   by simply setting it to zero.
2) __tcp_trim_head() changes skb->len thus we need
   to recalculate tso_factor
3) BUG check that tcp_retrans_try_collapse() does not
   try to collapse packets with non-1 tso_factor
4) The Solaris FIN workaround in tcp_retransmit_skb()
   changes packet size, need to fixup tso_factor

A disconnected dentry can hold an inode active after the last link has
been removed.  The file will not then be truncated and removed until
memory pressure flushes the disconnected dentry from the dcache.

This problem can be resolved by making sure that an inode never has
both a connected and a disconnected dentry.

This is already the case for directories (as they must only have one
dentry), but it is not the case for non-directories.

This addresses it by:
 - changes d_alloc_anon to make sure that a new disconnected dentry is
   only allocated if there is currently no (hashed) dentry for the
   inode. (Previously this would noramlly be true, but a race was
   possible).
 - changes d_splice_alias to re-use a disconnected dentry on
   non-directories as well as directories.
 - splits most of d_find_alias out into a separate function to make
   the above easier.

Problem originally reported by Nikita Danilov.

Acked by Al Viro ("It looks sane"), and Jakob Oestergaard reports this
fixes his problems. Further pushed by Christoph Hellwig.

The current code allocating the DART has a couple of bugs, first
it's called on all machines including the ones who have no DART
(oops), and then it tries to access the device-tree using the
"of_chosen" pointer before it was initialized.

The enclosed patch fixes these.

Looks like we never needed them, since that bug has been there forever,
I didn't get the right base for the IO cycles on the G5 host bridge
in the first place (I probably misinterpreted some OF forth code or
something like that).

No problems reported other than Linus typo in an unbuildable driver from
the last one.

This one adds tty_ldisc_flush and also makes tty_wakeup do the queue
wake as discussed with Paul.  I've then propagated these functions
through all the drivers.  This means most drivers don't know about the
ldisc locking and instead call generic functions that look after it. 
The result is the removal of a lot of duplicate code both for ldisc
referencing and historical code for handling tty ldisc wakeup semantics.

A nice side effect is that by adding versions of the two helpers we can
switch most of the drivers over before changing the core tty code if
preferred.

Silly thinko/typo, it needs to check the newly allocated memory for

This patch moves the following files in /proc:
	/proc/net/rt_cache_stat 	/proc/net/stat/rt_cache
	/proc/net/ip_conntrack_stat	/proc/net/stat/ip_conntrack
	/proc/net/arp_cache_stat	/proc/net/stat/arp_cache
	/proc/net/clip_arp_cache_stat	/proc/net/stat/clip_arp_cache
	/proc/net/dn_neigh_cache_stat	/proc/net/stat/dn_neigh_cache

This allows a generic statistics tool to scan for all available statistics
by doing readdir(2) on /proc/net/stat

It also adds a special first 'template' line to rt_cache and ip_conntrack
in order to facilitate compatibility once somebody adds new fields to the
output lines.

WARNING: 
	This breaks existing rtstat.c and ctstat.c userspace programs
	(hopefully for the last time).  rtstat is non-existant or broken in
	major distributions anyway, and ctstat is too new for any distros
	having it picked up.  Therefore, we justify this breakage.

A new unified statistics tool for routing cache, connection tracking and
neighbour cache is under development and will be included with iproute2.
